SANTA CLARA — Jim Harbaugh ended Wednesday’s media session with a pointed defense of why he spoke so strongly last year in support of wide receiver A.J. Jenkins.

The 49ers traded Jenkins on Monday to the Kansas City Chiefs in exchange for Jon Baldwin, a deal that came 13 months after Harbaugh took to task the “clueless” media that criticized Jenkins.

“I know a lot of people have been making some sport of A.J. and Jonathan and my comments and that type of thing,” Harbaugh said in unsolicited fashion.

“I really feel the same as I did a year ago when I made those comments. That I don’t think it’s fair to bully or label a young player. Though I fully understand that people are entitled to their opinion and their perspective.

“However, I prefer that the criticism — I would appreciate if the criticism is directed toward me. I’m responsible and I certainly accept that.

“Actually, I welcome it.”

Harbaugh wasn’t as terse as he was a year ago on the subject, when he vowed an “I-told-you-so” moment to the media’s “scribes, pundits and so-called experts.”

“Like I just said, of course I’m going to defend a young player when I believe he’s being bullied or labeled, before even his first practice,” Harbaugh said.

Jenkins, last year’s first-round draft pick, went on to produce zero receptions in scarce action as a rookie. Through two exhibition games this month, he had one catch, which he fumbled.

Asked to clarify what he’s “responsible” for, Harbaugh replied: “I’m responsible. I’m responsible for helping pick the draft picks and fully responsible for coaching the players up. So I willingly accept those responsibilities.”

Quarterback Colin Kaepernick welcomed his coach’s approach, stating: “I think it’s great when the coach is going to take your side, the players’ side, and do whatever he can to make you comfortable and be successful on the field.”

Compounding the 49ers’ 0-3 start is that their past two defeats have come against NFC West rivals. Up next is another division opponent Sunday, when the 49ers visit the Arizona Cardinals.
